This is a hand-cranked model of a 8 cylinder radial engine.
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel (source: Wikipedia).
To assemble, print the following parts, and follow the assembly procedure.
Cylinder Block
Handle
Rotor
Pin
Hub Bottom (Requires support)
Hub Top
Piston (x 8ea)
Rod (x 7ea)
The "un-sectioned" cylinder block is also uploaded, but I have not tried printing it (I am not entirely sure if it the parts can be assembled into it).
I designed in some slack in each of the parts, but you may want to make sure that all parts fit with sufficient clearance for smooth motion.
